I'm freaking out.. 😩😭

I'm 9 weeks and 5 days today. My first ultrasound is tomorrow. I'm kinda freaking out. I had cramps with no spotting or anything like that but every time I feel a cramp I start freaking out. I was told I would have a hard time getting pregnant.... and I did. It toon over 2 years. My baby father and I aren't on good terms anymore. I just don't wanna worry. Any suggestions to help me stop freaking out so much? 😩😭 also is it possible to start showing at 9 weeks? 🤔 this is my first pregnancy and I have so many questions!
